Begin completing the square.

Move the constant term to the right:

Add '-3' to each side of the equation.
3 + 3x + -3 + x2 = 0 + -3

Reorder the terms:
3 + -3 + 3x + x2 = 0 + -3

Combine like terms: 3 + -3 = 0
0 + 3x + x2 = 0 + -3
3x + x2 = 0 + -3

Combine like terms: 0 + -3 = -3
3x + x2 = -3

The x term is 3x.  Take half its coefficient (1.5).
Square it (2.25) and add it to both sides.

Add '2.25' to each side of the equation.
3x + 2.25 + x2 = -3 + 2.25
